Kinematically Redundant Manipulator
being solved to determine the corresponding required joint values, 8(t;). A kinematically redundant manipulator can, in general, satisfy an end-effector positioning constraint, x(t;), with an infinite family of joint values satisfying (2). The underlying premise for advocating the use of redundant manipulators for critical applications is that if a joint should fail, then the redundancy of the ...

متن کاملA local measure of fault tolerance for kinematically redundant manipulators
When a manipulator suuers a joint failure, its performance can be signiicantly affected. If the failed joint is locked, the resulting manipulator Jacobian is given by the original Jacobian, except that the column associated with the failed joint is removed. The rank of the resulting Jacobian then determines if the manipulator still has the ability to perform arbitrary end-eeector motions. Unfor...
متن کاملTeleoperation Performance with a Kinematically Redundant Slave Robot
This paper studies the effects of three methods of kinematic redundancy resolution on teleoperation performance with a redundant slave robot in telemanipulation. First, we derived three kinematic redundancy control modes expressing different trade-offs between kinetic energy level, joint usage, and joint limit avoiding. To validate our algorithms we performed simulations, autonomous robot tests...
متن کاملFailure Tolerant Operation of Kinematically Redundant Manipulators
The high cost involved in the retrieval and repair of robotic manipulators used for remediating nuclear waste, processing hazardous chemicals, or for exploring space or the deep sea, places a premium on the reliability of the system as a whole. For such applications, kinematically redundant manipulators are inherently more reliable since the additional degrees of freedom (DOF) may compensate fo...
